 Email
etiquette: I will not discuss mathematics (e.g. solutions or hints of
solutions to HW problems) via email. Office hours and lectures are the
best venue for that purpose. However, if you have any type of
administrative questions regarding this class, please do not hesitate
to send me short and to the point email messages.
GETTING HELP
Help with mathematical problems:
 Section: Ask
questions in section  this is one of the main reasons why sections
exist.
 Office Hours: You
are strongly advised to take full advantage of your professor's and
ta's office
hours.
 Classmates: Sometimes
a classmate can help. Sometimes you can learn by working out problems
together with your classmates.
